5:42 PM: With the Alaskan Way Viaduct out of commission this weekend, the exits on the Spokane Street Viaduct – east half of the West Seattle Bridge – are carrying more traffic. That might be complicating matters now that there’s a four-car crash near the 4th Avenue South exit. Big backup on the bridge, according to the nearest cam:

Just drove the westbound spokane st. Accident looked really bad, hope everyone is ok. Traffic eastbound still a parking lot all the way to the steel mill. Doesn’t look like it will be moving any time soon.
